## About the role

We’re looking for a Senior Software Engineer to join our security team - the group responsible for keeping 70+ million creators, and everything they’ve built, safe. Linktree is the front door to a creator’s whole digital presence, which makes it a target: account takeover, abusive content, scraped data, third-party integrations with more access than they should have. This role is about building the systems that make those attacks hard. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 4+ years of professional software engineering experience, with meaningful time spent on security, infrastructure, identity or another domain where getting it wrong is expensive
- Strong full-stack skills across our core stack: TypeScript, Node.js , React, GraphQL, PostgreSQL or MySQL and AWS, with the ability to move across layers to ship a fix end-to-end
- Working knowledge of application security fundamentals: the OWASP Top 10, authentication and authorisation, secrets management, cryptography in practice, and the common attack classes against consumer platforms
- Experience threat modelling a real system and turning the output into shipped work, rather than a document nobody reads
- A track record of shipping changes to a high-traffic, critical path safely - feature flags, staged rollouts, migrations and backwards compatibility
- Fluency with AI-assisted development (Claude, Cursor, Codex and similar), including how to prompt, validate and refine what these tools produce - and where they introduce risk
